What is claimed is: 1. A rotor supporting structure of a windmill for wind power generation, comprising; a rotor assembly having bosses located above and below, a support extending radially from each boss, and a longitudinal blade supported by a front edge of the support of both above and below bosses, the above boss having an upwardly-facing bearing receiving hole, the below boss having a downwardly-facing bearing receiving hole; and a frame assembly having a stationary downwardly pending cylindrical bearing rotatably received in the upwardly-facing bearing receiving hole and a stationary upwardly extending cylindrical bearing rotatably received in the downwardly-facing bearing receiving hole. 2. A rotor supporting structure of a windmill according to claim 1, wherein the support is a transversal blade which yields a lift force in the rotative direction when the vertical blade is forced by a wind. 3. A rotor supporting structure of a windmill according to claim 1, wherein the frame assembly is provided with a lock means to keep the longitudinal blade in a restrained condition at a position adjacent to a zone in which the longitudinal blade rotates. 4. A rotor supporting structure of a windmill according to claim 1, wherein the frame assembly and the rotor assembly are provided with a pair of repelling magnets in which the combination of the both magnets braces the rotor assembly upward. 5. A rotor supporting structure of a windmill for wind power generation, comprising: a rotor assembly having bosses located above and below, a support extending radially from each boss, and a longitudinal blade supported by a front edge of the support of both above and below bosses; and a frame assembly having a roller bearing retaining the boss of the rotor assembly rotatively around a vertical shaft center and a leg holding the roller bearing at a position away from a ground, wherein the frame assembly is provided with a ring placed horizontally at a position adjacent to a zone in which the vertical blade rotates, and the rotor assembly is provided with a wheel running along the ring. 6. A rotor supporting structure of a windmill for wind power generation, comprising: a rotor assembly having bosses located above and below, a support extending radially from each boss, and a longitudinal blade supported by a front edge of the support of both above and below bosses; and a frame assembly having a leg holding the roller bearing at a position away from a ground, and a joint part connecting the legs in an equal interval circumferentially, wherein the joint part comprises plural spokes connected to a roller bearing extending radially and a pair of rings located above and below connected to the legs connecting an outer edge of the spoke to each other; wherein a roller bearing retains the boss of the rotor assembly rotatively around a vertical shaft center and the rotor assembly is set between the above and below rings. 7. A rotor supporting structure of a windmill according to claim 6, wherein the ring is provided with a lock means to keep a top or bottom of the longitudinal blade in a restrained condition. 8. A rotor supporting structure of a windmill according to claim 6, wherein the spoke is provided with a lock means to keep the longitudinal blade in a restrained condition. 9. A rotor supporting structure of a windmill according to claim 6, wherein a magnet is set at a bottom of the longitudinal blade and magnets which repels the magnet set at a bottom of the longitudinal blade, are set at the bottom ring. 10. A rotor supporting structure of a windmill according to claim 6, wherein the frame comprises three rings and the rotor assembly having a generator is arranged into two stages, upper and lower. 11. A rotor supporting structure of a windmill according to claim 6, wherein a wheel is arranged at a bottom of the rotor assembly running along the below ring. 12. A rotor supporting structure of a windmill for wind power generation, comprising; a rotor assembly having bosses located above and below, a transversal blade extending radially from each boss, and a longitudinal blade having supported by a front edge of the transversal blade of both above and below bosses; and a frame assembly having a roller bearing retaining the boss of the rotor assembly rotatively around a vertical shaft center and a leg holding the roller bearing at a position away from a ground, wherein the longitudinal blade has a wing shape which yields a rotative force when forced by a lateral wind and the transversal blade has a wing shape which yields a lift force when forced by a lateral wind.
